So I have a 2003 Jeep Wrangler. Has 54k on it, I bought it about 3 years ago. I've had to fill it up with coolant twice now from the couldn't reservoir. I'm not seeing any leaks anywhere, not seeing any milky residue in my oil, I do smell something like coolant or something burning after driving it for a while. I've been told it may be a blow head gasket or cracked head, like I said I'm not seeing any coolant in my oil. Trying to find the solution so I can fix myself, thanks!
